st: RE: Re: correlations

What you ask for still sounds like a round-about way of getting what you want.
You can just ensure that the -statsby- results include the sample size. Then you have enough information in the file to calculate inferential results, with some extra assumptions.
Alternatively, -corrci- at

with correlations
gives you confidence intervals, arguably more informative than just starring results as if they were hotels or movies, although still often problematic.
As these look like data in time, a different comment is to underline that the assumptions underlying correlation significance calculations include mutual independence.

I am applying the following command over my
database to get a stata file with correlations (working on Stata
11.2):
statsby, by(isin2) saving(correld): corr liq sap if ano>=2008 & dsap0810==1
where isin2 is an identification number, liq and sap are the variables
where correlation should be applied and ano and dsap0810 are some
filters I need to apply. My question to the list is if there is some
additional command that I can use properly in order to have the same
output (ids and correlations for the selected periods) but instead of
having a separate file (correld.dta) to get the output on my results
window. Why do I ask this? because I would like to get the results
with their corresponding significance levels on the form of asterisks
(***).
